摘要： The present invention provides variable spot size illuminators that provide a light spot on a treatment plane by utilizing a zoom lens to direct light received from an image of a light source formed on an intermediate image plane onto the treatment plane. The zoom lens allows varying the size of the treatment spot while ensuring that the treatment spot exhibits parfocality. An illuminator of the invention can be utilized for performing a number of ophthalmic surgical procedures, such as, photocoagulation, transpupillary thermal therapy, and photodynamic therapy.

摘要： A lens design form is used for a viewing optical system or magnifier that includes a cemented doublet and a weak aspheric element, for example, made of acrylic, and having a diffractive kinoform surface superimposed on the surface profile of the aspheric element. The design significantly reduces both chromatic aberrations and minimizes most of the monochromatic aberrations of the optical system or magnifier. By allowing the lens design form to produce an image on a curved surface, optical performance is improved further over the prior art systems because this allows the elements in the system to control the image blurring aberrations rather than having to also control field curvature. The human eye can accommodate for the curved field, and thus the curved field does not reduce image quality, but instead allows image quality to be enhanced. The viewing optical system also can be used for image projection.

摘要： A head-mounted display system for the viewing of video or other sources of imagery which comprises a mechanism allowing for a wide range of adjustments for presenting the display to the wearer. The head mounted display device is supported by a headband or other support structure with three independent adjustments giving the wearer a wide range of adjustment capability. One pivot adjustment is in a location in proximity with the ear, the other pivot adjustment is located in close proximity with the pupil of the eye, and a third adjustment allows for the display unit to be adjusted in or out from the wearers head so as to permit convenient use with glasses. The mechanism allows the display to be located within or outside the wearer's primary field of view by utilizing these multiple adjustment locations for the system. The display unit consists of viewing optics, fold mirrors, liquid crystal display devices, and a backlight unit. By folding the light inward to nearly co-located display devices, a single backlight unit can be used.
